only numbers in form

Hi!
I have a validation script that i want to keep, but i have a question about how i write so that the script can check that only numbers is alowed, i want an alert to appear when there is an error, just like the rest of the script, se my code.

<script language="JavaScript" type="text/javascript">
<!--
function MCValidation()
{


if (document.mcform.frmParticipantPassword.value == "") {

alert("Password is required!");
document.mcform.frmParticipantPassword.focus();
return false;

}

if (document.mcform.frmParticipantPassword.value.length < 6) {

alert("Password must contain at least six characters!");
document.mcform.frmParticipantPassword.focus();
return false;

}

return true;

}

// -->
</script>
